Spawn rape is specifically defined as the act of a person of having their crosshair or damage radius of a projectile aimed specifically at the place where a persons model or character spawn. This act of camping a particular spawn and then instantly killing the opponent or putting them at a large damage defecit from their initial spawn health as they respawn is spawn rape.

Spawn rape has been in multiplayer games from their very inception.

It is the map designers job to prevent spawn raping by designing levels that allow the player to move significantly from a protected spawn in order to be able to retaliate and be able to fire back on a camper, thus preventing spawn rape.

OMGZ! That guy is just camping right in front of that corner spawn and killing them instantly. SPAWN RAPE!!!

Happens occasionally in online death match games. when you spawn and without warning you find yourself dead again by someone who either 1)camps - waits in a place for people to spawn, or 2) is just in the right place at the right time

v. 1. When a individual is killed immediately after spawning in a multiplayer shooter, such as Call of Duty.
2. When someone spawns directly in front of you and you spawn-rape them
3. In Call of Duty Black Ops, when you find a tactical insertion and wait and kill the player who spawns there eventually.

Steve: Damn! I should've known someone would have found my tactical insertion.
John: Yeah, they totally spawn-raped you bad
